(57) A rotor having an improved structure capable of achieving enhanced durability is disposed in a motor, the rotor including a sleeve having a shaft hole, through which a motor shaft extends, rotor cores spaced apart from one another in a circumferential direction of the rotor, and permanent magnets each disposed between adjacent ones of the rotor cores such that the permanent magnets are arranged in a radial manner about the sleeve. First and second cover plates may be disposed at opposite sides of the permanent magnets in an axial direction. Each of the first and second cover plates may include a shaft receiving hole to receive the motor shaft. The rotor may include a plurality of support members each having a magnet support portion arranged to support an outer end of a corresponding one of the permanent magnets in a radial direction of the rotor.
